[bug-libunistring] libunistring 1.1 ABI and LTV_... variable values

[Brian Inglis]

Hi folks,

Packaging 1.1 on latest Cygwin, DLL version jumps from 2 to 5.

It appears that libunistring was upgraded from library version 4:0:2 to 5:0:0:

$ grep ^LTV_ libunistring-1.?-1.x86_64/src/libunistring-1.?/lib/Makefile.am
libunistring-1.0-1.x86_64/src/libunistring-1.0/lib/Makefile.am:LTV_CURRENT=4
libunistring-1.0-1.x86_64/src/libunistring-1.0/lib/Makefile.am:LTV_REVISION=0
libunistring-1.0-1.x86_64/src/libunistring-1.0/lib/Makefile.am:LTV_AGE=2

libunistring-1.1-1.x86_64/src/libunistring-1.1/lib/Makefile.am:LTV_CURRENT=5
libunistring-1.1-1.x86_64/src/libunistring-1.1/lib/Makefile.am:LTV_REVISION=0
libunistring-1.1-1.x86_64/src/libunistring-1.1/lib/Makefile.am:LTV_AGE=0

but does not this imply that 1.1 library interfaces are compatible only with 
this version, which is not implied in the NEWS or ChangeLog, stating only that 
data and algorithms have been updated to Unicode 15, and documenting 
iconveh_question_replacement_character added in 1.0.

Should the library version perhaps be 5:0:3 if only additions have been made?
